  • You could say the same for a finite element model. A junior engineer with just 4 years of training can solve, explicitly, the deflection at the center of a slender, simple-simple beam of prismatic section and produce an exact (if slightly incorrect) answer. Building a FEM of the same can solve the problem and take longer (to make the model) with similar accuracy, both of which are good enough for design work.

    Only a fool wouldn’t have a FEM around though, as it can solve problem that would take centuries for a human to solve. They may as well make a cartoon with the child digging a 3” hole in beach sand and then showing a backhoe making a jagged edged hole of the same size.








  • Mostly. If your locality is served by Amtrak - and only a few dozen cities are out of the 3 million square miles of ConUS - then it can be somewhat convenient and cost effective if you plan your travel more than 2-3 months in advance. It’s about 2/3 the speed of car travel, but more comfortable, generally. If you buy tickets less than 3 weeks ahead the prices are about 4x what they are for booking at 3-6 months out. Also, unless you live in one of the 2-3 hub areas, trains run only once or twice a day. For comparison, Last time I checked it’s like £70 to go from London to Aberdeen and takes 7 hours and trains leave every hour or two. From Roanoke to New York - 80 miles closer than the UK route I know of - it’s $200, 9 hours, and only two trains run per day - the first departs at 6:20am, the second at 4:15p (and gets in around 2am). It’s only a 7.5 hour drive and $40-50 in gas to go from Roanoke to NYC, and it’s pretty easy to park outside the city and take a commuter train in.

    Oh, and there’s no workable hub and spoke system due to the few trains and long travel times. My daughter is just 300 miles away at school and the city has a train stop. It’s a 5 hour drive one way. It takes two days and 3 train changes to get from her city to the closest station to me, about a 45 minute drive away. It’s ridiculous.







  • No, you have to type the whole post out. Re-read it to bask in the insightfulness, and correct the usage errors and autocorrects. Then decide that you’ve said your peace, and don’t really want some numbnut responding with a poorly thought out, single sentence reply. Delete the text, knowing you had the chance to vent.

    Then go find another post and do the same. At 5pm you can then close your browser, look at your desk, and wonder why you didn’t get any work done that day.
